Hi @jennagoldman,

That’s correct. I can confirm that the New Universal Login still does not allow you to limit the country codes or configure a default country code for MFA phone enrollment. This is mentioned in [this post](https://community.auth0.com/t/can-we-limit-the-allowed-country-codes-for-sms-mfa-enrolment/115218/6).

Although you cannot limit the country codes, you can use a [send phone message action](https://auth0.com/docs/customize/actions/flows-and-triggers/send-phone-message-flow) script to restrict users from performing MFA unless they have a phone number from a valid country by checking `event.message_options.recipient` attribute for the user’s mobile phone number. (Reference: [How to Filter or Lock MFA Mobile Number Country Codes in New Universal Login](https://community.auth0.com/t/how-to-filter-or-lock-mfa-mobile-number-country-codes-in-new-universal-login/88800))

Please let me know if you have any questions.

Thanks,  
Ruebe
